What Is Vitamin B3 (Niacin)?

[dropcap]N[/dropcap]iacin is an essential water-soluble B vitamin that is required by all cells of the body.

During digestion of food containing it, niacin (the form in food) is changed in the small intestines to the active form niacinamide (niacin plus an amide group), which is then absorbed into the bloodstream. 

Niacinamide is converted by the body into co-enzymes which are present in all cells. These are niacinimide adenine dinucleotide (NAD) and NADP. NADP is formed when the body adds a phosphate to NAD.

Q: How do these enzymes work?

A: These enzymes function in oxidation-reduction reactions essential for release of energy from carbohydrates, fats, and proteins and are needed as components for more than 200 enzymes involved in metabolism.

In addition to producing energy, niacinamide is essential for healthy skin and the mucosal lining of the digestive tract, normal functioning of the brain and nervous system, and production of steroid hormones in adrenal glands and hormones in sex glands.  Functions are more fully described below.

Urinary excretion of niacin cannot be detected when vitamin intake is below the required levels. On the other hand, when intake exceeds saturation in the body, the vitamin and/or its metabolites are actively excreted into urine to prevent excessive toxicity of the vitamins.1

What Is Folate?

[dropcap]F[/dropcap]olate, also called folic acid or vitamin B9, is a family group of essential water-soluble B vitamins needed to produce healthy blood cells and other tissue cells.

Folate is required for healthy blood cells, the metabolism of at least 5 amino acids, the production of DNA, RNA and tRNA (genetic material), the normal development of a baby in the womb, male and female fertility, and regulation of homocysteine (amino acid) by reduction of harmful blood levels in conjunction with vitamin B6 and vitamin B12.

Urinary excretion of folate cannot be detected when vitamin intake is below the required levels. On the other hand, when intake exceeds saturation in the body, the vitamins and/or their metabolites are actively excreted into urine to prevent excessive toxicity of the vitamins.1

Brain Blood Flow Abnormalities 

blood perfusion gluten celiac diseaseWhat Are Brain Blood Flow Abnormalities?

[dropcap]B[/dropcap]rain blood flow abnormalities, or cerebral perfusion abnormalities, such as spasm of blood vessels causing inadequate blood flow to the brain, are characterized by impaired brain function and thinking.

Q: What is cerebral perfusion?

A: Cerebral perfusion is the flow of blood in the brain. Blood supply to the brain comes from 4 major vessels: 2 carotid arteries and 2 vertebral arteries.

Cerebral perfusion abnormalities can be diagnosed using perfusion computed tomography (CT). CT scan is a technique that allows rapid qualitative and quantitative evaluation of cerebral perfusion by generating maps of cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT). The technique is based on the central volume principle (CBF = CBV/MTT) and requires the use of commercially available software employing complex deconvolution algorithms to produce the perfusion maps.

Perfusion CT has been found to be useful for noninvasive diagnosis of cerebral ischemia (diminished blood flow) and infarction (no blood flow) and for evaluation of vasospasm (intermittent blood flow through vessels).1
